Abstract
Systems and methods include a computer-implemented method for determining hydrocarbon fuel concentrations. A thin Cyclic Olefin Copolymer (COC) film of a COC layer with a conductive trace that completes an electrical circuit is sputtered. The thin COC film is positioned under tension so that the thin COC film is configured to dissolve upon contact with alkyl aromatic compounds present in hydrocarbon fuels. A sample of a hydrocarbon fuel is positioned on the thin COC film. A determination is made, in response to positioning the sample, that a dissolution of the thin COC film has broken the conductive trace and has rendered the electrical circuit open. A time duration is measured from an introduction of the sample during positioning to an opening of the electrical circuit. A concentration of the hydrocarbon fuel in the sample is determined based on the time duration.
